Congrats on the new ride @gwrabbit from a 2018 SHO owner in east central WI. Is this your first GEN4?
I'm in the Oshkosh area. I saw a SHO on the way back from work (41 Northbound).Enjoy. - had a 2015 Ingot Silver as well...great cars - both were non- PP. I have been leasing so haven't done any tuning would love to do so as it really wakes the car up. What part of WI do you live in...I am in east central. There are a few SHOs around here but few and far between for sure.
Cool...what color was the one u saw on 41..my 2018 is Burgundy Velvet Metallic - PIA to keep clean. I think I saw Jasontheruger's highly modified SHO on Hwy 23 eastbound last week between Rosendale and Ripon..it is bada$$. Chk it out...he is on this forum occasionally. I tagged him but haven't heard back...it had to be his...not too many in this area modified like his.
